I couldn't get this to work as VBScript (that requires too many line
continuation characters), but I think the following JScript should
work. The call to WShell.Run() pops another window, so I included a
time.sleep() call to make that slow enough to notice. Fortunately
JScript and python both will happily ignore integer and string
literals at the beginning of the file, and JScript comments look like
python floor division. I ran this at the command line like so:
C:\>cscript bdist.js "Python26\python.exe"
Here's the script:
4 // 3; '''
;
if (WScript.Arguments.Count() < 1)
WScript.Echo("usage: " + WScript.ScriptName + " <path to python>");
else
WScript.CreateObject("WScript.Shell").Run(WScript.Arguments.Item(0) + " " +
WScript.ScriptFullName, 1, true); /*
'''
# start of python script
from time import sleep
print("hello from python")
sleep(5)
# end of python script */
